applications or for reading the resistance of potentiometer input. Default range is 0-40 K Ohms; the module can also be
configured for 0-20 K, 0-10 K, or 0-5 K Ohms. Resistance probes must be isolated from each other.
Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted
controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for
PC-based control or for use as intelligent remote I/O for an Allen-Bradley RSLogix PLC system, such as ControlLogix,
MicroLogix, or CompactLogix.
Compatibility: This module can be used with SNAP PAC brains and R-series controllers. It can also be used with legacy
SNAP Ethernet-based brains.
